Aurora® Field Generators (FGs) emit a low-intensity, varying electromagnetic field that establishes the measurement volume in which the EM sensors’ positions and orientations are tracked. There are five Aurora FGs, each with a distinct measurement volume, form factor, and mounting options that can be applied to different OEM navigation system workflows and procedures, and set up within the operative space.
Planar 20-20 Field Generator
The Planar 20-20 FG is a versatile field generator with numerous mounting options that allow it to be easily positioned above or around the patient bed without impeding the physical workflow. The Planar 20-20 FG has the largest measurement volume of all Aurora FGs. This general-purpose FG is commonly used for OEM system navigation applications in interventional radiology, spinal surgery, and ENT surgery.
Planar 10-11 & 10-11H Field Generators
The smallest Aurora field generators, Planar 10-11 and 10-11H have a small, lightweight, ergonomic design that allows handheld tracking of localized areas. The 10-11H version has a centre aperture (measuring ø34 mm) that enables the user to run an ablation needle or handheld drill through the FG. The Planar 10-11 and 10-11H FGs can be used in OEM system navigation applications in interventional radiology, and for the Planar 10-11H FG, orthopaedic trauma applications.
Tabletop Field Generator
The Tabletop FG measures just 3.4 cm thick, allowing it to be placed between the patient and the table. This unique placement removes any physical obstruction within the operative space and field of view.
